I really wish there was an emote that simply said 'SORRY!' when I accidentally hit a teammate and need to express my remorse. I also don't want them hitting me when I try to drag them away from the edge of Ichiban or something.
I hit my teammate on Castleween like, four times last night and he naturally didn't trust me the rest of the match.
Devs, help me be polite and remorseful!
